  1. HW 1 – Mortgage Calculator • Implemented as standalone Java Program • Swing based GUI • XML Processing using JAXP

  2. HW1 – Writing XML // write XML for this month fileout.write("<MonthlyAmortization>"); fileout.newLine(); fileout.write("<Month>"+ i + "</Month>"); fileout.newLine(); fileout.write("<Balance>"+ String.format("%.2f",balance) + "</Balance>"); fileout.newLine(); fileout.write("<Payment>"+ String.format("%.2f",payment) + "</Payment>"); fileout.newLine(); fileout.write("<Interest>"+ String.format("%.2f",interest) + "</Interest>"); fileout.newLine(); fileout.write("<Equity>"+ String.format("%.2f",equity) + "</Equity>"); fileout.newLine(); fileout.write("<Assessments>"+ String.format("%.2f",assessments) + "</Assessments>"); fileout.newLine(); …

  3. HW1 – XML Parsing & Validation // Create parser factory javax.xml.parsers.DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); // Make it a validating parser dbf.setValidating(true); dbf.setNamespaceAware(true); dbf.setAttribute("http://xml.org/sax/features/validation", true); dbf.setAttribute("http://apache.org/xml/features/validation/schema", true); // create a parser javax.xml.parsers.DocumentBuilder parser = dbf.newDocumentBuilder();

  4. HW2 – Output Schema <?xml version = "1.0" encoding = "UTF-8"?> <xsd:schema xmlns:xsd = "http://www.w3.org/2001/XMLSchema"> <xsd:element name = "PaymentSchedule"> <xsd:complexType> <xsd:sequence> <xsd:element name = "Name" type = "xsd:string" /> <xsd:element name = "BeginMonth" type = "xsd:integer" /> <xsd:element name = "Currency" type = "xsd:string" /> <xsd:element name = "MonthlyPayment" maxOccurs = "unbounded"> <xsd:complexType> <xsd:sequence> <xsd:element name = "DueDate" type = "xsd:date" /> <xsd:element name = "Payment" > <xsd:complexType> <xsd:simpleContent> <xsd:extension base="xsd:decimal"> <xsd:attribute name="made" type="xsd:boolean" use="required"/> </xsd:extension> </xsd:simpleContent> </xsd:complexType> </xsd:element> <xsd:element name = "Balance" type = "xsd:decimal" /> <xsd:element name = "Principal" type = "xsd:decimal" /> <xsd:element name = "Interest" type = "xsd:decimal" /> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema>

  5. HW2 – Currency Conversion <?xml version="1.0"?> <currencies> <currency> <code>eur</code> <name>Euros</name> <convFactor>0.76</convFactor> </currency> <currency> <code>usd</code> <name>Dollars</name> <convFactor>1.0</convFactor> </currency> <currency> <code>cad</code> <name>Canadian dollars</name> <convFactor>1.15</convFactor> </currency> </currencies>
